Aminolase should be taken with protein rich foods and all protein supplements including the following: whey, milk, casein, soy, pea, rice and hemp. Protein supplements are one of the richest sources of all nine essential amino acids that the body is unable to produce on its own; however all protein must first be processed into a usable form, which includes essential amino acids and beneficial peptides (i.e., Di and Tri-peptides). To be effective, protein must be broken down into a smaller particle size within approximately 90 minutes of consumption. This transit time represents the time from which protein passes from the stomach through the small intestine where digestion/absorption primarily occurs; from there it will be assembled into muscle building protein (a bio-usable form). Undigested protein will simply be excreted from the body, resulting in increased kidney stress and wasted amino acids, essentially pouring your expensive protein supplement down the toilet.
